Removed FnvHash and transformed the rest to FxHashmap (#39233)

Browse source 
This should be the final PR for the Hash Function series that is
trivial.

Of note: I decided to transform `HashMapTracedValues<Atom,..>` to use
FxBuildHasher. This is likely not going to improve performance as Atom's
already have a unique u32 that is used as the Hash but it safes a few
bytes for the RandomState that is normally in the HashMap.

Testing: Hash function changes should not change functionality, we
slightly decrease the size and unit tests still work.
